Apocrine sweat gland adenocarcinoma: A rare case report and review.

INTRODUCTION: Primary apocrine sweat gland carcinoma (PASGC) is an extremely rare neoplasia whose management and treatment are still evolving. The only curative therapy is wide local excision. Many patients have metastasis at the time of the diagnosis, mainly because this neoplasm has been misdiagnosed as some benign skin lesions. PRESENTATION OF CASE: We herein report a case of a 72-year-old-man with PASGC affecting the axilla and regional lymph nodes that underwent surgical resection and lymphadenectomy at our Institution. This is the first case reported in Brazil. DISCUSSION: Our observation suggests just a MRI as necessary to study tumoral limits and lymph nodes and a full surgical excision with free margins is decisive for success. CONCLUSION: Despite the PASGC be a rare cancer and require expensive tests, knowledge of this disease is critical to reduce costs in medical services without availability of investment.

Oncogenic hypophosphatemic osteomalacia: From the first signal of disease to the first signal of healthy.

INTRODUCTION: The physical incapacitation of the oncogenic hypophosphatemic osteomalacia (OHO) can be catastrophic and can lead to deformities, metabolic and organic instability and death. The only positive outcome is through early diagnosis by the clinical suspicion. At this moment, medical center infrastructure is also a keypoint. PRESENTATION OF CASE: This case report is about a 60-year old woman with multiple fractures, gradual loss of strength and muscle mass and limiting deformities in two years of evolution until the diagnostic. DISCUSSION: The lack of knowledge of this disease causes a delay in diagnosis that can bring deformities to the patient, as well as death. Is crucial that is hypothesized to carry out the necessary tests, since they are expensive and not always available. CONCLUSION: This case reinforces the importance to understand the OHO and tumoral search, once this lesion is, in most cases, imperceptible to physical examination or several imaging studies.

A case of oncogenic osteomalacia owing to inguinal tumor.

The oncogenic hypophosphatemic osteomalacia is a very incapacitating disease and the mortality rate, mainly due to metabolic disorder, depends on the early diagnosis, since the surgery is curative. The major difficulty is to consider this kind of disease in patients with complex clinical presentation. Moreover, medical centers have to provide a good diagnostic infrastructure because these tumors, in most cases, are small and do not have an obvious site. This case report is about a man with a rapid loss of strength and muscle mass, which had his diagnosis in a late, culminating in significant deformities and organic dysfunctions with clinical repercussions. However, the fast diagnosis with appropriate tests determined the stop point of the evolution of disease and marked the beginning of metabolic recovery. This case reinforces the global problem health care infrastructure and the access to diagnostic equipment, demonstrating the impact on the patient's health of our service.
